This adaptation is part of the research discipline of Hypotheses Engineering (HE) where customer needs can be seen as hypotheses that need to be tested iteratively by conducting experiments together with the customer. So far, modeling support and associated traceability of this iterative process are missing. Both, in turn, are important to document the adaptation to the customer needs and identify experiments that provide most evidence to the customer needs. To target this issue, we introduce a model-based HE approach with a twofold contribution: First, we develop a modeling language that models hypotheses and experiments as interrelated hierarchies together with a mapping between them. While the hypotheses are labeled with a score level of their current evidence, the experiments are labeled with a score level of maximum evidence that can be achieved during conduction. Second, we provide an iterative process to determine experiments that offer the most evidence improvement to the modeled hypotheses. We illustrate the usefulness of the approach with an example of testing the business model of a mobile application."}],"volume":391,"has_accepted_license":"1","status":"public","date_created":"2020-05-04T12:27:38Z","author":[{"full_name":"Gottschalk, Sebastian","first_name":"Sebastian","id":"47208","last_name":"Gottschalk"},{"first_name":"Enes","orcid":"0000-0002-5967-833X","full_name":"Yigitbas, Enes","last_name":"Yigitbas","id":"8447"},{"full_name":"Engels, Gregor","first_name":"Gregor","id":"107","last_name":"Engels"}],"publisher":"Springer International Publishing","publication":"Business Modeling and Software Design","keyword":["Hypothesis Engineering","Model-based","Customer Need Adaptation","Business Model","Product Features"],"file_date_updated":"2020-07-14T09:28:33Z","file":[{"file_size":267658,"creator":"sego","file_id":"17380","date_updated":"2020-07-14T09:28:33Z","content_type":"application/pdf","relation":"main_file","date_created":"2020-07-14T09:25:30Z","file_name":"BMSD20.pdf","access_level":"open_access"}],"intvolume":" 391","_id":"16934","conference":{"start_date":"2020-07-06","name":"10th International Symposium on Business Modeling and Software Design ","location":"Potsdam","end_date":"2020-07-08"},"citation":{"chicago":"Gottschalk, Sebastian, Enes Yigitbas, and Gregor Engels. “Model-Based Hypothesis Engineering for Supporting Adaptation to Uncertain Customer Needs.” In Business Modeling and Software Design, edited by Boris Shishkov, 391:276–86.

These techniques allow for the joining of dissimilar materials and thus enable multi-material design, while thermic joining methods reach their limits. Semi-tubular self-piercing riveting is an important mechanical joining technology. The rivet production, however, is costly and time-consuming, as the process consists of several process steps including the heat treatment and coating of the rivets in order to achieve an adequate strength and corrosion resistance. The use of high nitrogen steel as rivet material leads to the possibility of reducing process steps and hence increasing the efficiency of the process. However, the high tool loads being expected due to the high strain hardening of the material are a major challenge during the rivet production. Thus, there is a need for appropriate forming strategies, such as the manufacturing of the rivets at elevated temperatures. Prior investigations led to the conclusion that forming already at 200 °C results in a distinct reduction of the yield strength. To create a deeper understanding of the forming behaviour of high nitrogen steel at elevated temperatures, compression tests were conducted in a temperature range between room temperature and 200 °C. The determined true stress – true strain curves are the basis for the further process and tool design of the rivet production. Another key factor for the rivet manufacturing at elevated temperatures is the influence of the process temperature on the tribological conditions. For this reason, ring compression tests at room temperature and 200 °C are carried out. The friction factors are determined on the basis of calibration curves resulting from the numerical analysis of the ring compression process. The investigations indicate that the friction factor at 200 °C is significantly higher compared to room temperature. This essential fact has to be taken into account for the process and tool design for the rivet production using high nitrogen steel."}],"volume":1,"status":"public","date_created":"2020-10-12T08:23:27Z","quality_controlled":"1","keyword":["High nitrogen steel","Self-piercing riveting","Joining by forming","Bulk forming","Strain hardening"]},{"intvolume":" 14","_id":"19973","citation":{"ieee":"B.

Each rivet geometry fulfils the requirements of the materials within a limited range. In the present investigation, an improved rivet geometry is developed, which permits the reliable joining of two material combinations that could only be joined by two different rivet geometries up until now. Material combination 1 consists of high-strength steel on both sides, while material combination 2 comprises aluminium on the punch side and high-strength steel on the die side. The material flow and the stress and strain conditions prevailing during the joining process are analysed by means of numerical simulation.

Disturbances can be compensated by an adaption of process parameters, but finding suitable parameters manually is difficult and time-consuming. This paper presents a physical model of the ultrasonic wire bonding process including the friction contact between tool and wire. This model yields novel insights into the process.

Aligning ourselves to the ongoing critical discussions of interiorization in psychology, we explore the crucial notion of space by highlighting language as sociocultural and dialogical activity performed by other-oriented individuals. We discuss space in terms of the “language spacetime”, a symbolic, embodied formation of mutually positioned speaking and listening selves. This leads beyond the “inside-outside” container metaphor and allows for a reformulation of interiorization. Interiorization is conceptualized as a continuous series of different, though mutually related movements between self and other and self and self that lead to and are supported by specific formations in language activity: reversion, transposition, and decoupling. Along a short passage of a video-based interview, we trace the reversion of dialogical positions within the addressivity constellation of the two interlocutors, their interactive creation of a heterotopic spacetime, and the decoupling of one speaker's psychological activity from the concrete here-and-now and the present other by moving and acting into this new sphere. Interiorization appears as a movement at the border of past, present, and possible future(s).","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1016/j.newideapsych.2017.12.001","date_updated":"2022-07-18T09:21:16Z","publication_identifier":{"issn":["0732-118X"]},"publication_status":"published","department":[{"_id":"424"}],"title":"Reconsidering interiorization: Self moving across language spacetimes"},{"language":[{"iso":"eng"}],"type":"dissertation","citation":{"ama":"Meyer T.

They can extend their lifetime at the cost of lowered performance or vice versa. This can be used to adapt failure behavior according to a maintenance plan, thus increasing availability while using up system capability fully. To facilitate setup, a control algorithm independent of a degradation model is desired. A closed loop control technique for reliability based on a health index, a measure for system degradation, is introduced. It uses self-optimization as means to implement behavior adaptation. This is based on selecting the priorities of objectives that the system pursues. Possible working points are computed beforehand using model-based multiobjective optimization techniques. The controller selects the priorities of objectives and this way balances reliability and performance. As exemplary application, an automatically actuated single plate dry clutch is introduced. The entire reliability control is setup and lifetime experiments are conducted. Results show that the variance of time to failure is reduced greatly, making the failure behavior more predictable. At the same time, the desired usable lifetime can be extended at the cost of system performance to allow for changed maintenance intervals. Together, these possibilities allow for greater system usage and better planning of maintenance."}],"user_id":"210","title":"Optimization-based reliability control of mechatronic systems"},{"page":"1-11","type":"journal_article","citation":{"ieee":"A.

Reliability of these transducers is an important aspect in their application. Prognostics, which involve continuous monitoring of the health of technical systems and using this information to estimate the current health state and consequently predict the remaining useful lifetime (RUL), can be used to increase the reliability, safety, and availability of the transducers. This is achieved by utilizing the health state and RUL predictions to adaptively control the usage of the components or to schedule appropriate maintenance without interrupting operation. In this work, a prognostic approach utilizing self-sensing, where electric signals of a piezoelectric transducer are used as the condition monitoring data, is proposed. The approach involves training machine learning algorithms to model the degradation of the transducers through a health index and the use of the learned model to estimate the health index of similar transducers. The current health index is then used to estimate RUL of test components. The feasibility of the approach is demonstrated using piezoelectric bimorphs and the results show that the method is accurate in predicting the health index and RUL.","lang":"eng"}],"title":"Estimation of Remaining Useful Lifetime of Piezoelectric Transducers Based on Self-Sensing","user_id":"55222"},{"language":[{"iso":"eng"}],"page":"215-218","type":"conference","citation":{"apa":"Ho, N., Kaufmann, P., & Platzner, M.

The most common ontology for semantic data, schema.org, is supported by all major search engines and describes over 500 data types, including calendar events, recipes, products, and TV shows. As of today, users wishing to pass this data to their favorite applications, e.g., their calendars, cookbooks, price comparison applications or even smart devices such as TV receivers, rely on cumbersome and error-prone workarounds such as reentering the data or a series of copy and paste operations. In this paper, we present Semantic Data Mediator (SDM), an approach that allows the easy transfer of semantic data to a multitude of services, ranging from web services to applications installed on different devices. SDM extracts semantic data from the currently displayed web page on the client-side, offers suitable services to the user, and by the press of a button, forwards this data to the desired service while doing all the necessary data conversion and service interface adaptation in between. To realize this, we built a reusable repository of service descriptions, data converters, and service adapters, which can be extended by the crowd. Our approach for linking services to websites relies solely on semantic data and does not require any additional support by either website or service developers. We have fully implemented our approach and present a real-world case study demonstrating its feasibility and usefulness.","lang":"eng"}],"user_id":"11871","publication":"2017 IEEE International Conference on Web Services (ICWS)","keyword":["Services","Websites","Semantic Data","schema.org","Data Conversion","Interface Adaptation","Mediation"],"publisher":"IEEE","author":[{"id":"11308","last_name":"Wolters","full_name":"Wolters, Dennis","first_name":"Dennis"},{"id":"11871","last_name":"Heindorf","orcid":"0000-0002-4525-6865","full_name":"Heindorf, Stefan","first_name":"Stefan"},{"first_name":"Jonas","full_name":"Kirchhoff, Jonas","last_name":"Kirchhoff","id":"39928"},{"last_name":"Engels","id":"107","first_name":"Gregor","full_name":"Engels, Gregor"}],"date_created":"2018-11-26T11:49:31Z","status":"public"},{"date_updated":"2023-08-02T11:36:30Z","doi":"10.1109/tetc.2017.2771441","language":[{"iso":"eng"}],"title":"Self-Adjusting Monitor for Measuring Aging Rate and Advancement","department":[{"_id":"48"}],"publication_identifier":{"issn":["2168-6750","2376-4562"]},"publication_status":"published","intvolume":" 8","_id":"29462","issue":"3","page":"627-641","type":"journal_article","year":"2017","citation":{"short":"S.

Progressive age information should provide the age state that the system is in, and the rate that it is being aged at. In this paper, we propose a structure that monitors certain paths of a circuit and detects its gradual age growth, and provides the aging rate and aging state of the circuit. The proposed monitors are placed on a selected set of nodes that represent a timing bottleneck of the system. These monitors sample expected data on these nodes, and compare them with the expected values. The timing of sampling changes as the circuit ages and its delay increases. The timing of sampling will provide a measure of aging advancement of a circuit. To assess the efficacy of the proposed method and compare it with other state-of-the-art aging monitors, we use them on selected nodes of the execution unit of different processors, as well as some circuits from ITC99 benchmarks. The results reveal that the precision of our proposed method is between 0.12 (ns) to 0.401 (ns).

Copper allows higher electrical, thermal and mechanical loads than aluminum, which currently is the most commonly used material in heavy wire bonding. This is the main driving factor for increased usage of copper in high power applications such as wind turbines, locomotives or electric vehicles. At the same time, usage of copper also increases tool wear and reduces the range of parameter values for a stable process, making the process more challenging. To overcome these drawbacks, parameter adaptation at runtime using self-optimization is desired. A self-optimizing system is based on system objectives that evaluate and quantify system performance. System parameters can be changed at runtime such that pre-selected objective values are reached. For adaptation of bond process parameters, model-based self-optimization is employed. Since it is based on a model of the system, the bond process was modeled. In addition to static model parameters such as wire and substrate material properties and vibration characteristics of transducer and tool, variable model inputs are process parameters. Main simulation result is bonded area in the wiresubstrate contact. This model is then used to find valid and optimal working points before operation. The working point is composed of normal force and ultrasonic voltage trajectories, which are usually determined experimentally. Instead, multiobjective optimalization is used to compute trajectories that simultaneously optimize bond quality, process duration, tool wear and probability of tool-substrate contacts. The values of these objectives are computed using the process model. At runtime, selection among pre-determined optimal working points is sufficient to prioritize individual objectives. This way, the computationally expensive process of numerically solving a multiobjective optimal control problem and the demanding high speed bonding process are separated. To evaluate to what extent the pre-defined goals of self-optimization are met, an offthe- shelf heavy wire bonding machine was modified to allow for parameter adaptation and for transmitting of measurement data at runtime. This data is received by an external computer system and evaluated to select a new working point. Then, new process parameters are sent to the modified bonding machine for use for subsequent bonds. With these components, a full self-optimizing system has been implemented."}],"user_id":"210","title":"Reliable Manufacturing of Heavy Copper Wire Bonds Using Online Parameter Adaptation","author":[{"last_name":"Meyer ","first_name":"Tobias","full_name":"Meyer , Tobias"},{"last_name":"Unger","first_name":"Andreas","full_name":"Unger, Andreas"},{"last_name":"Althoff","full_name":"Althoff, Simon","first_name":"Simon"},{"full_name":"Sextro, Walter","first_name":"Walter","id":"21220","last_name":"Sextro"},{"full_name":"Brökelmann, Michael","first_name":"Michael","last_name":"Brökelmann"},{"first_name":"Matthias","full_name":"Hunstig, Matthias","last_name":"Hunstig"},{"first_name":"Karsten","full_name":"Guth, Karsten","last_name":"Guth"}],"quality_controlled":"1","keyword":["Self-optimization","adaptive system","bond process","copper wire"],"department":[{"_id":"151"}],"publication":"IEEE 66th Electronic Components and Technology Conference","status":"public","project":[{"_id":"92","grant_number":"02 PQ2210","name":"Intelligente Herstellung zuverlässiger Kupferbondverbindungen"}],"date_created":"2019-05-27T09:17:26Z"},{"title":"Self-Aware and Self-Expressive Systems – Guest Editor's Introduction","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C2","_id":"14"},{"_id":"34","name":"Self-Adaptive Virtualisation-Aware High-Performance/Low-Energy Heterogeneous System Architectures","grant_number":"610996"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"78"}],"doi":"10.1109/MC.2015.205","date_updated":"2022-01-06T06:53:19Z","language":[{"iso":"eng"}],"user_id":"16153","ddc":["000"],"status":"public","has_accepted_license":"1","date_created":"2018-03-23T14:06:12Z","volume":48,"file":[{"file_name":"07163237.pdf","date_created":"2018-11-02T15:47:45Z","access_level":"closed","file_id":"5313","creator":"ups","file_size":5605009,"relation":"main_file","success":1,"date_updated":"2018-11-02T15:47:45Z","content_type":"application/pdf"}],"author":[{"last_name":"Torresen","full_name":"Torresen, Jim","first_name":"Jim"},{"first_name":"Christian","orcid":"0000-0001-5728-9982","full_name":"Plessl, Christian","last_name":"Plessl","id":"16153"},{"first_name":"Xin","full_name":"Yao, Xin","last_name":"Yao"}],"publisher":"IEEE Computer Society","file_date_updated":"2018-11-02T15:47:45Z","publication":"IEEE Computer","keyword":["self-awareness","self-expression"],"issue":"7","_id":"1772","intvolume":" 48","type":"journal_article","year":"2015","citation":{"chicago":"Torresen, Jim, Christian Plessl, and Xin Yao. “Self-Aware and Self-Expressive Systems – Guest Editor’s Introduction.” IEEE Computer 48, no. 7 (2015): 18–20. https://doi.org/10.1109/MC.2015.205.","ama":"Torresen J, Plessl C, Yao X.

Especially technology-based self-service channels have found their way into the 21st century service economy. While research embraces these channels for their cost-efficiency, it has not examined whether a shift from personal to self-service affects customer–firm relationships. Drawing from the service-dominant logic and its central concept of value-in-context, we discuss customers’ value creation in self-service and personal service channels and examine the long-term impact of these channels on customer retention. Using longitudinal customer data, we investigate how the ratio of self-service versus personal service use influences customer defection over time. Our findings suggest that the ratio of self-service to personal service used affects customer defection in a U-shaped manner, with intermediate levels of both self-service and personal service use being associated with the lowest likelihood of defection. We also find that this effect mitigates over time. We conclude that firms should not shift customers toward self-service channels completely, especially not at the beginning of a relationship.
